Monism attempts to reconcile the spirit-matter duality in one of two ways: either it reduces all things to matter, in which case we have materialistic monism, or else it goes in the opposite direction and becomes spiritualistic monism. Monism, then, is true insofar as it refuses to accept any dualism. It fails, however, by attempting to reconcile the two terms without leaving the ‘order’ to which they belong, and this cannot be done. That is to say, it is impossible to reconcile the spirit-matter dualism while remaining at the level of the relative, because at the relative level, the opposition is ‘real’ and ‘irreducible’. The only way to truly reconcile them is to transcend the relative and approach the universal, which is to say, by looking at the problem from the point of view of metaphysics, which monism cannot do.
